Legris 0102 04 00 Compression Tube Union Brass 4mm

Product Description

The LEGRIS 0102 04 00 is a brass compression tube union designed to join two compression-end tube lines in a single straight fitting. It provides a leak-resistant, tool-assisted connection without the need for soldering or thread sealants. Rated to 300 psi maximum working pressure and a temperature range of -40 degrees F to 210 degrees F, this union suits pneumatic and fluid-handling lines in demanding industrial and commercial environments. The brass construction resists corrosion and handles moderate chemical exposure. The fitting is compliant with ATEX, PED, CNOMO E07.21.115N, Prop 65, REACH, and RoHS standards, making it suitable for regulated applications across multiple industries.

This union fitting is used where a technician needs to extend, repair, or connect two tube runs with matching outside diameters. The 4mm outside diameter sizing fits small-bore tubing common in instrumentation, pneumatic control lines, and light fluid-distribution systems. Typical install scenarios include OEM machine assemblies, process control panels, and compressed-air distribution networks in commercial and light industrial facilities. A licensed mechanic, pipefitter, or instrumentation technician would normally install this fitting during new construction or maintenance work.

Compatibility

Designed as a direct-fit compression union for 4mm outside diameter tubing used in pneumatic, instrumentation, and light fluid-handling systems. Confirm tube outside diameter and working pressure rating before installation.

Installation Notes

Installation should be performed by a qualified pipefitter, instrumentation technician, or mechanical contractor. Depressurize and isolate the line completely before removing or installing any compression fitting. Ensure tubing is cut cleanly and squarely, and that the tube end is fully seated in the fitting body before tightening the compression nut. Follow applicable system design standards and any site-specific codes governing pneumatic or fluid-line work.
